Question
In 1842, _______, a leading railway engineer and
professor of civil engineering at University College, London, presented a detailed proposal for a system of railways in India. ÂSolution
Charles Blacker Vignoles (1793-1878), Professor of Civil Engineering, University College London, submits a report to the East India Company on the possibility of constructing a railway network in India (Hurd and Kerr 1). This is very much a colonial project, with an eye to managing the country and facilitating trade. On "the eve of a period of 'railway mania' a vast country like India, with her resources and wealth," naturally attracts "the notice of many enterprising Englishmen".
Simplify the following expression:
(3/5 of 250 + 40% of 150) ÷ (0.75 of 80)
?% of 320 = 40% of 40 × 5
35% of 500 × 22% of ? = 847
(〖(0.5)〗^(1/3) × 〖(1/125)〗^(1/4) × 〖25〗^(1/6) ×〖(6.25)〗^(2/3))/(〖(2.5)〗^(2/3) × 5^(-1/2) × 〖(1/5)〗^(-2)×〖3125�...
Simplify: 72 ÷ 6 × 3 − 8 + 4
2048 × 1824 ÷ 76 = (? - 212) × 64
Simplify the following expression:
36 x 3.6 ÷ 0.5 ÷ ? = 64
Simplify the following expression:
  (525 +175) ² - (525 – 175) ² / (525 × 175)
